Specification oi' Patent i Application filed June 23, 1917.` SeriallNo. 176,571.

To all 'whom may concern: Y

Be it known that I, VILLIAM E. Seilwin nassen, ya citizen ol? the United States, residing in the county ot Perkins and State o't' South Dakota, have invented certain .new

and useful Improvenlents in Nutlloclis; and lf do hereby declare the Yfollowing to be a :[iull, clear, and exact description of the invention, such as will enable others skilled in the art to which. it appertains to make and use the saine.

This invention relates to imljn'ovenlents in a nut lock and has 'for one of its objects the provision ci device ol. this character, espe# cially adapted for use on railroad rail joints 'for preventing the nuts on thebolts .from becoming' accidentally detached therefrom.

Aiiother object oit this invention is to provid-e a plate for each nut and which is apertured to receive the bolt and has formed on :its side edges, 'flanges :lor engaging the nut to lock the plate to the nut.

A 'further object of this invention is the y provision ol a resilient bar or member on the bolts and adapted to be engaged by iianges formed on the upper and lower ed ges of the plates to prevent them :trom rotating with the nuts.

A still further object oit this invention is the provision ci? a nut lock of the above stated ch aractergwhich shall be simple, durable and eHicient, and which may be manufactured and sold at a comparatively low cost.

llVith these and other objects in view, as

will become more apparent as the descrip-`Y tion proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more 'fully described and claimed.

For a complete understanding ofrmy in vention, reference is to be had to the following description and accompanying drawing; in which: l p

Figure l is a side elevation of a nut lock constructed in accordance with my inven tion,

Fig. 2 is a longitudinal sectional view. of the same, i

Fig. 3 is a transverse sectional view illus tratino' the connection between the and the resilient bar or member,

Aplates Patented Mar. 5, 191s.

Figlis a detail perspective view of one oll the plates.

Referring in detail to the drawing, the nn- ]neral l indicates one rail ol a railroad rail Joint, while the numeral 2 indicatesthe other rail,` the rails being; connected together by the ordinary fish plates 3, which have the bolts el :tor comlecting them to the rails l and E. The bolts Ll have the ordinary nuts 5 tliireaded thereon :for preventing the bolts from becomingr detached :from the fish plates and rails.

lt is usually cnstoniary `to employ two bolts to each rail as shown in Fig. l, and to proven t the nuts upon thc'bolts from becoming: detachedV therefrom, I have provided a resilient bar or member 6 having each endl bowed at 7 and apertured to receive the bolt.

Each ol the bolts have mounted thereon, a plate 8, which. plat-e is disposed between the bowed portions 7 of the har or member 6 and the nuts 5. The plates 8 are constructed :from Vsheet metal and have formed upon their side edges, flanges 9, which are adapted to be bent into engagement with the sideV faces of the nuts 5 as shown in Fig. 2 'for lockingthe plates to the nuts. Rearwardly directed flanges l0 are :formed upon the up per and lower edges of the plates 8 and adapted to engage the upper and lower edges of the bar or member (l tor locking the plates to said bar or member, and it will therefore be seen that the bowed portions of the bar or member G will always exert a pressure against the plates, which prevents the flanges 9 :from disengaging the nuts and the plates will be held against rotation upon the bolts by the flanges l0 engaging the upper and lower edges of the bar or member 6.

The openings in the bulged portions of the bar or member are oi. elongated liormationfor permitting the bar or member to move upon the bolts, whereby a construction is provided which will permit the `ar or member to ex crt pressure upon the plates and nuts at all times, thereby establishing' a joint t0 railmeans to thedevice.

While I have shown and described the pre-V V-erred"embodiinent ot' my invention, it will loo be understood that minor changes in construction, combination and arrangement of parts may be made Without departingfrom the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is: Y

l. In combination, a rail joint including lish plates and bolts having nuts thereon, plates carried by said bolts, flanges connecting the plates to the nuts, a resilient mem-` ber carried by the bolts, and means on the upper and lower edges of the plates for engagement with the upper and lower edges of said member.

2. In combination, a rail joint including fish plates and bolts having nuts thereon, plates carried by saidV bolts, means connecting the plates to the nuts, a member having y each end bowed and apertured to receive t bolts, and flanges formed upon the platee and engaging the upper and lower edges of Athe member to lock `the plates against rota- Gopies of this patent may be obtained for live cents each, by addressing the Commissioner `of Patents,
